Drive plate for roll machining lathe

The utility model aims to solve the problem that the existing roll machining efficiency is low and provides a drive plate for a roll machining lathe. The drive plate comprises a plate body, an ejector block and two or more drive rods; the ejector block is fixed to the center of the plate body which is round, through a bolt; the drive rods are evenly distributed and fixed on a circle centering on the center of the plate body. The drive plate is applied to cutting of bored rolls which are not equipped with shafts, the problem that shaking occurs to high speed cutting in the original roll machining process is eliminated, roll cutting speed is increased, the rolls are equipped with the shafts after being cut, and production efficiency of the rolls is improved accordingly.
